Diversity of insertion/excision sites of Tn-Dha1 and ISDha1 copies^a

^aThe diagram at the top depicts the overall Tn-Dha1 structure.

^bThe same letter code is used in Fig. 5.

^cTn-Dha1 and ISDha1 sequences are indicated in brackets; direct repeats are italicized; black, dark gray, light gray, and white boxes indicate specific regions around Tn-Dha1 and ISDha1 copies. Nucleotides (nt) coming from either the left or the right flanking site after ISDha1 excision or illegitimate recombination are underlined.

^dData taken from reference 12.

^eNumbers of nucleotides missing from the direct flanking regions of ISDha1 excision are listed in parentheses.
